Application iuedrebruar 'ai, 1912. Serial mic-e044.

T 0 all whom it may concern:

Be it known that I, FREDERICK RICHARD SIMMS,L subject of the King of Great Britain, residin Middles'ex, ngland, have invented new and useful Improvements in Magneto-Electric Machines, of which the following is a speci- My invention relates to improvements in combined ignitionand illuminating devices for use on motor roadvehicles, and to that class of appliance or installation in which the current for both lighting and ignition is obtained from a magneto-electric machine.

According to my invention I make use of i a magneto-electric machine having two pairs of pole-pieces, between one pair of which there'rotates a laminated armature for 'generating the lighting current and between the other pair of which there is arranged a Siemens armature for generatingthe ignition current. i Y

"In practice I find it advantageous to make use of a permanent magnet which is built up of three separate magnets arranged side by side, the center magnet being longer than the twooutside magnets and carrying the pole-pieces for the ignition armature, while the two outer or shorter magnets carry polepieces between which rotates the armature for generating the lighting current.

To enable the invention to be fully understood, I will describe it by referenceto the accompanying drawings, in which Figu're'l is a sectional side elevation of amagneto-electric machine adapted. for combined ignition and illuminating purposes according to theinvention. Fig. 2 is a section I on the line 2-2, Fig. 1, Fig. 3 is a section on the line 3-3, Fig. 1, Fig. 4 is aside view of themagnet.

The apparatus illustrated in Figs. 1 ,to 4:

shaped magnets are arranged side by side. The two outside magnets are composed of three curved strips 05,?) and 0 and are secured at their ends to the upper pole-pieces (Z, (Z between which there rotates the armature e curved or horseshoe-shaped strips f, g and h, the lowermost of these strips f being extended downward and carryingl the lower pole-pieces i, 2' between which t ere rotates I Specification of Letters Patent.

tion, the arms of certain of said ma Patented oct. 5, 19.15;

a Siemens armature j, ,for generating the ignition current, the two upper strips ex tending, similarly to the sections 1) and c of the outside magnets, to the upper pole-pieces cl, d to which they are similarly secured.

. The armature j is driven from the spindle j in the usual manner and the armature 6 -1S driven from the said spindle through the medium of the toothed gears It, In.

It will be understood from the foregoing descr ption that when the magneto-electric machine is driven in the usual way from the engine acurrent is generated in each of the two armatures e and j, the current from the armature e belng distributed and used for lighting purposes, and that from the arma- J ture j being distributed to the sparking plugs ot the engine cylinders for ignition purposes in the usual manner.
